Avidemux 2.6 has big problem with ProjectX's demuxed mpeg files

Hi,

I am upset over Avidemux - my long-time prefered video editor :D - because older Avidemux 2.5 is stopped 3 months already, and Avidemux 2.6 is still (=propably forever?) totally unusable for Xvid-AVI making.
I usually make my own-use xvid-rip from TS DVB-T stream (remuxed with ProjectX).

But with remuxed mpeg files I cant use time-bar for seeking I-frames, etc. When I am sliding on time-bar, it is jumping totally randomly. You cant set the exact frame, as you wish.

And where is classical XVID encoder plugin  (alá 2.5)?

Finally, I am frustrated from 2.6.

Yes, I heard about this feature.  :P
But is it fully operable, as ProjectX alternative?
ProjectX is very foolproof, it knows repair strong damaged, for example with many damaged frames in TS stream, etc. (my own experiences).
Maybe is problem in ffmpeg (re-muxing)...

I am using this BAT file:

for /r %%x in (*.ts) do (
"C:\Programy\projectx\ProjectX.jar" "%%x"
del "%%~nx.ts.xml"
"C:\Programy\projectx\ffmpeg.exe" -threads 4 -i "%%~nx.m2v" -i "%%~nx.mp2" -target pal-dvd -vcodec copy -acodec copy "%%~nx.mpg"
del "%%~nx.m2v"
del "%%~nx.mp2"
del "%%~nx.xml"
del "%%~nx_log.txt"
)

If you have a sample processed by projectX that avidemux 2.6 has issue with, it would help.

upload a 20 MB sample +- 5 seconds to an upload site and provide link here so mean can have a look at the problem.

I think, that problem is with ffmpeg muxer (vid. my BAT file), not ProjectX.
I suprised, that 2.5 can process it fully OK..., but 2.6 not (very bad, unusable seeking on time-bar).

Can you provide an original none processed video sample file to? One before you processed it with ffmpeg?

Sorry, I cant. I deleted it. But native TS streams (grabbed from USB DVB-T stick via DV scheduler - http://sydney.edu.au/engineering/it/~efax/DVScheduler.html) are evidently processed OK via 2.6.

Looks like avidemux does not find any timing information in the projectX file
So either :
* They are present but avidemux does not find them (bug)
* They are not present, and the stream is buggy

2.5 does not care at all about timing information, so it can process the file, but cannot keep the a/v sync.

workaround :

ffmpeg -i yourfile.mpg foobar.ts

and then edit foobar.ts
